Default
Each classifier requires a unique number in the range 1 to 498. When you
define a classifier, the first information you supply is the classifier number.
The number you specify dictates which type of classifier you are defining.
The default classifier number is 499, which you cannot remove or modify.
Default
This is because all traffic passes through the QoS engine and the system
needs a classifier to handle all packets.
If you want to define a flow classifier (for routed IP packets only),
specify a value in the range of from 1 to 399. This allows you to
specify IP source and/or destination addresses as well as TCP or UDP
socket information.
If you want to define a nonflow classifier (for bridged or routed
packets), specify a value in the range of from 400 to 498. (See the list
of predefined nonflow classifiers in Figure 82.) For nonflow classifiers,
you cannot classify to the IP address or socket level.
